How would I make these object legs?
Here's one possible way:

Start with a round cube (quadsphere preset) from Add Mesh Extra
Objects add-on.

Delete top half of the object


Select groups of faces that will make up the legs


Change pivot point to individual origins with
Ctrl+. (period)

Run loop tools circle operator on the selected faces W &gt;L &gt; C


Extrude by nomals with Alt+E then adjust geometry as you need.
